Abstract

A realization of voltage-mode transfer functions with feedforward input signal for third-order active-R filter using an oprational amplifier has been presented. This filter is useful for high frequency operation, monolithic IC implementation and is easy to design. The single circuit gives three filter functions, low pass, high pass and band pass. This filter circuit can be used for differentQ and f0 with high passband gain. This gives better stop band attenuation and sharper cut-off at the edge of the passband.
